Research team led by Kim Kum Chol, the laboratory head from the Faculty of Electronics, developed various high-efficiency portable analyzers with self-technology and is gaining public favors from various fields of national economy.
Colon bacilli analyzer developed by the research team analyzes colon bacilli in water, whose measurement range is 0~1 000/mL, minimum disjointing capability is 1/mL. Toxic gas analyzer analyzes CO, CO2, SO2, NO2, O3, H2S etc. in the air and its measurement range is 0~1 000ppm, minimum disjointing capability is 0.1ppm, analyzing time is less than 10s. The measurement range of procedure saltiness gauge used in the analysis of saltiness for underground ultra-salty water, soya and bean paste production process of basic foodstuff factories, saltiness of seawater, boiler feed water etc. is 0~30%, minimum disjointing capability is 0.1ppm. Of turbidity analyzer, measurement range is 0~10NTU and minimum disjointing capability is 0.1NTU. They are now developing their research work for further enhancing the accuracy of their analyzers.

Head of lab, Jang Ki Ho and other researchers at Faculty of Heat Engineering have developed a high-voltage water heater of 1~3MW. The advantages of this over the conventional electric heating boiler and the boilers that use heavy oil, gas or coal include less consumption of electric power, less amount of space for installation, less initial investment and environmental friendliness.
In particular, this heater serves as a major means to relieve the load shake in the generation of electricity by renewable energy.
